Exactly what @Remigija said! 1 small drop in each nostril (one at a time) and then immediately bulb suction or nose frida to get anything out. Your definitely do not want to keep anything in the nose.
My 2 month old has sinus issues as well. I use saline drops and suck out the mucus with the nose Frida every other day when he’s stuffy. Surprised at how much mucus continues to come out! Unfortunately he also gets a little cough every now and then, probably also from mucus buildup, so I also use saline with a nebulizer and this seems to help him.
Speak to a doctor !
Could be bronchitis
@Tyy is right. Saline drops and the nose Frida does wonders
Thank you everyone! I used the saline and the suction device, worked well!
If you breast feed try your milk instead of nose drops:)
